```Use Transpose[] to get your points (please avoid initial capital letters for

In:=
a = {{x1, x2, x3, x4, x5, x6}, {y1, y2, y3, y4, y5, y6}};

In:=
ListPlot[Transpose[a]];

will get you what you want. If you have duplicate points in Transpose[a},
then

In:=
Union[Transpose[a]]

will get rid of them.
